That makes testing a bit difficult.

Don't know of any. But you could instruct the compiler and linker to use a 64 Bit environment as a target. You will need the 64 Bit libs installed for linking. The effort to do this is much larger than setting up a 64 Bit Suse. Rent a root server with 64 Bit Suse if you don't want to spend much money or need things fast. You will need a computer for testing anyway.
Maybe you don't need that at all, as all 64 Bit Distros bring the 32 Bit libs along with them. I have not found a program compiled for 32 Bit environment that doesn't work on a 64 Bit system.
